I'm a new user for ubuntu, I buy Samsung N148+ and installed it with Ubuntu 10.04.
At first everything is fine except for the brightness control, so I update with update manager.
After the update, the problem is arisen, when i press the Fn + up/down key or Fn + F4,F5... , the desktop stop running, not totally stop, i can still move my mouse,but the left and right button of the mouse don't work, and the keyboard stop working, i can't input any key from the keyboard too. The only thing i can do is press the restart button under my N148 or cut off the power...
Please help me...thank's
